The diverse older HIV-positive population: a national profile of economic circumstances, social support, and quality of life

The objectives of this study were to provide a national profile of socioeconomic circumstances of the middle-aged and older population living with HIV and to evaluate variations in social support and quality of life (QOL) across age and socioeconomic subgroups, controlling for indicators of disease progression. The design used was a cross-sectional analysis of nationally representative interview data on HIV-infected individuals collected in the HIV Cost and Services Utilization Study. Multiple measures of social support and QOL were used. Bivariate comparisons of outcomes across categories of age and exposure category were performed; multivariate analyses to isolate the effect of older age on outcomes within exposure categories were performed, controlling for socioeconomic and clinical co-variates. Study results indicate that older gay men with HIV/AIDS are a predominantly white population and more likely to have health insurance than their younger counterparts; 38% were employed and 48% reported incomes of more than $25,000. Older injection drug users (IDUs) with HIV/AIDS are a predominantly black population with a particularly high concentration of disadvantages; only 11% were employed and 74% reported incomes of less than $10,000. Older IDUs reported especially low levels of physical functioning and emotional support in comparison with their younger counterparts, whereas older gay men did not significantly differ from younger gay men in these respects. The authors conclude that characteristics and care needs of the older HIV-positive population are very diverse and vary sharply by exposure route. Interventions need to be tailored to the needs of these distinct subpopulations, with an emphasis on development of supportive care interventions for older IDUs.

Income-related differences in the use of evidence-based therapies in older persons with diabetes mellitus in for-profit managed care

OBJECTIVES

To determine whether income influences evidence-based medication use by older persons with diabetes mellitus in managed care who have the same prescription drug benefit.

DESIGN

Observational cohort design with telephone interviews and clinical examinations.

SETTING

Managed care provider groups that contract with one large network-model health plan in Los Angeles County.

PARTICIPANTS

A random sample of community-dwelling Medicare beneficiaries with diabetes mellitus aged 65 and older covered by the same pharmacy benefit.

MEASUREMENTS

Patients reported their sociodemographic and clinical characteristics. Annual household income (> or =$20,000 or <$20,000) was the primary predictor. The outcome variable was use of evidence-based therapies determined by a review of all current medications brought to the clinical examination. The medications studied included use of any cholesterol-lowering medications, use of 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins) for cholesterol lowering, aspirin for primary and secondary prevention of cardiovascular disease, and angiotensin-converting enzyme (ACE) inhibitors in those with diabetic nephropathy. The influence of income on evidence-based medication use was adjusted for other patient characteristics.

RESULTS

The cohort consisted of 301 persons with diabetes mellitus, of whom 53% had annual household income under $20,000. In unadjusted analyses, there were lower rates of use of all evidence-based therapies and lower rates of statin use for persons with annual income under $20,000 than for higher-income persons. In multivariate models, statin use was observed in 57% of higher-income versus 30% of lower-income respondents with a history of hyperlipidemia (P =.01) and 66% of higher-income versus 29% of lower-income respondents with a history of myocardial infarction (P =.03). There were no differences by income in the rates of aspirin or ACE inhibitor use.

CONCLUSION

Among these Medicare managed care beneficiaries with diabetes mellitus, all of whom had the same pharmacy benefit, there were low rates of use of evidence-based therapies overall and substantially lower use of statins by poorer persons.

Physician specialization and antiretroviral therapy for HIV

BACKGROUND

Since the introduction of the first protease inhibitor in January 1996, there has been a dramatic change in the treatment of persons infected with HIV. The changing nature of HIV care has important implications for the types of physicians that can best care for patients with HIV infection.

OBJECTIVE

To assess the association of specialty training and experience in the care of HIV disease with the adoption and use of highly active antiretroviral (ARV) therapy (HAART).

DESIGN

Observational cohort study of patients under care for HIV infection and their physicians.

PATIENTS AND SETTING

This analysis used data collected from a national probability sample of noninstitutionalized persons with HIV infection participating in the HIV Costs and Service Utilization Study and their primary physicians. We analyzed 1,820 patients being cared for by 374 physicians.

MEASUREMENTS

Rates of HAART use at 12 months and 18 months after the approval of the first protease inhibitor.

RESULTS

Forty percent of the physicians were formally trained in infectious diseases (ID), 38% were general medicine physicians with self-reported expertise in the care of HIV, and 22% were general medicine physicians without self-reported expertise in the care of HIV. The majority of physicians (69%) reported a current HIV caseload of 50 patients or more. In multivariable models controlling for patient characteristics, there were no differences between generalist experts and ID physicians in rates of HAART use in December 1996. When compared to ID physicians, however, patients being treated by non-expert general medicine physicians were less likely to be on HAART (odds ratio [OR], 0.32; 95% confidence interval [95% CI], 0.17 to 0.61). Patients being treated by low-volume physicians were also much less likely to be on HAART therapy than those treated by high-volume physicians (OR, 0.26; 95% CI, 0.14 to 0.48). These findings were attenuated by June 1997, suggesting that over time, the broader physician community successfully adopted HAART therapy. This finding is consistent with prior research on the diffusion of innovations.

CONCLUSIONS

Similar proportions of patients treated by expert generalists and ID specialists were on appropriate HAART therapy by December 1996 and July 1997. Patients treated by non-expert generalists, most of whom were the lowest-volume physicians, were much less likely to be on appropriate ARV therapy in the earlier time period. Our findings demonstrate that expert generalists who develop specialized expertise are able to provide care of quality comparable to that of specialists.

Usage patterns of over-the-counter phenazopyridine (pyridium)

OBJECTIVES

Little is known about how the public uses formerly prescription medications that are available over-the-counter (OTC). This study examines whether consumers inappropriately use and substitute a recently widely distributed OTC urinary analgesic, phenazopyridine, for provider care.

DESIGN/SETTING

We conducted a cross-sectional survey of a stratified cluster random sample of OTC phenazopyridine purchasers (N = 434) in 31 Los Angeles retail pharmacies over 5 months. Recruited by shelf advertisements, participants were 18 years or older who purchased a phenazopyridine product. Each completed a 25-item self-administered anonymous questionnaire. Inappropriate use was defined as 1) having medical contraindications to phenazopyridine, or 2) not having concurrent antibiotic and/or provider evaluation for the urinary symptoms.

RESULTS

The survey response rate was 58%. Fifty-one percent of the respondents used OTC phenazopyridine inappropriately, and 38% substituted it for medical care. Multiple logistic regression analyses revealed that inappropriate use was correlated with having little time to see a provider (odds ratio [OR], 1.57; 95% confidence interval [95% CI], 1.26 to 1.96), receiving friend's or family's advice (OR, 1.25; 95% CI, 1.05 to 1.47), having prior urinary tract infections (OR, 0.49; 95% CI, 0.30 to 0.80), having used prescription phenazopyridine, (OR, 0.40; 95% CI, 0.25 to 0.63), and having back pain (OR, 0.34; 95% CI, 0.16 to 0.74). Similar correlates were found in those who substituted OTC phenazopyridine for provider care. Respondents with incorrect knowledge about phenazopyridine's mode of action had 1.9 times greater odds of inappropriate use and 2.2 times greater odds of substitution than those who had correct knowledge about this drug.

CONCLUSION

Inappropriate use of OTC phenazopyridine appears common. Increasing the public's knowledge about reclassified drugs may help to mitigate this problem.

Use of psychotropic medications among HIV-infected patients in the United States

OBJECTIVE

This study describes the prevalence and pattern of use of psychotropic medications by HIV-positive patients receiving medical care in the United States and the search for possible predictors of use.

METHOD

The HIV Cost and Services Utilization Study database was analyzed. From the estimated 231,400 HIV-positive patients in medical care in the contiguous United States, a probability sample of 2,864 adults who had paid at least one visit to their medical provider in early 1996 was selected. A representative group of 1,561 received the long form of the Composite International Diagnostic Interview and a questionnaire on psychotropic medications used during the previous 6 months; 1,489 patients (95.4%) completed the assessments.

RESULTS

An estimated 27.2% of HIV-positive patients took psychotropic medications in 1996. Antidepressants were the most commonly prescribed drug class (20.9% of patients), followed by anxiolytics (16.7%), antipsychotics (4.7%), and psychostimulants (3.0%). Among patients with major depression or dysthymia, 43.2% reported receiving antidepressants, and 34.3% reported receiving anxiolytics. Psychiatric comorbidity was associated with greater use of psychotropics. Use of psychotropics in general, and antidepressants in particular, was significantly lower among African Americans than whites or Hispanics. Among patients with mood disorders, 61.0% of whites, 51.4% of African Americans, and 66.7% of Hispanics reported use of antidepressant medications or some type of psychosocial intervention.

CONCLUSIONS

Psychotropics were commonly used by HIV-positive patients in medical care. About half of the patients suffering from depressive disorders did not receive antidepressants. Psychotropic drug use was lower among African Americans than other ethnic groups.

Effect of violence on utilization of services and access to care in persons with HIV

We analyzed the HIV Costs and Service Utilization Study data to determine the association of violence, assessed at baseline, with utilization of and access to health care at follow-up, among gay/bisexual male, heterosexual female, and heterosexual male HIV/AIDS patients. In multivariate analyses, male gay/bisexual violence victims had increased odds of reporting emergency department visits (odds ratio [OR], 1.74; 95% confidence interval [95% CI], 1.20 to 2.52), going without needed medical care because of expense (OR, 1.83; 95% CI, 1.06 to 3.18), and having poor ability to access medical specialists (OR, 1.96; 95% CI, 1.05 to 3.67). Further research is required to understand the association of violence with health care among gay/bisexual men with HIV/AIDS.

Insurance status of HIV-infected adults in the post-HAART era: evidence from the United States

In the United States, universal public insurance is only available for the elderly. But unlike most other major diseases, HIV/AIDS predominantly affects the nonelderly. The result is that insurance availability and public programme participation are linked to disease progression in a complicated way. This paper uses data from a unique, nationally representative sample of HIV-infected adults receiving medical care, to describe the relationship between disease progression and insurance coverage in the United States. We find that public insurance is the predominant source of coverage for those in care for HIV, and that coverage increases as disease progresses. Those with public coverage have substantial work experience and earnings capacity, but do not work. This suggests that reforms allowing HIV positive (+) patients to maintain public coverage while returning to work could increase employment and earnings significantly. More speculatively, it suggests that the United States system for financing health care is not well-equipped to deal with epidemics that afflict a population in its prime work years.

Measuring medication: do interviews agree with medical record and pharmacy data?

BACKGROUND

Medication measurement is crucial in assessing quality for chronic conditions yet agreement of alternate data sources remains uncertain.

OBJECTIVES

To evaluate medication agreement between interviews, medical records, and pharmacy data; to assess data source contribution to attributing medication exposure; and to describe the impact of combining data sources on models that predict medication use.

RESEARCH DESIGN

Prospective cohort study.

SUBJECTS

Probability sample of HIV-infected participants in the HIV Cost and Services Utilization Study.

MEASURES

Medications reported in 2267 interviews, 1936 medical records, and 457 pharmacy records were compared using crude agreement, kappa, and the proportion of average positive and negative agreement. The percent of medications reported in each source alone was used to assess their relative contribution to attributing exposure status. We performed weighted logistic regression in alternate data sources.

RESULTS

Kappa varied from 0.38 for nucleoside reverse transcriptase inhibitors to 0.70 for protease inhibitors, when comparing drug classes in interview versus medical record, interview versus pharmacy data, and medical record versus pharmacy data. The percentage of medications reported in medical records was greater than that reported in interviews or pharmacy data. Pharmacy data contributed little to the attribution of medication exposure. Adding medication data to interview data did not appreciably change analytic models predicting medication use.

CONCLUSIONS

For specific medications, agreement between alternative data sources is fair to substantial, but is lower for key drug classes. Relying on one data source may lead to misclassification of drug exposure status, but combining data sources does not change the results of analytic models predicting appropriate medication use.

HIV patients' experiences with inpatient and outpatient care: results of a national survey

CONTEXT

Little is known about HIV patients' care experiences.

OBJECTIVE

To assess HIV patients' experiences with inpatient and outpatient care, and to assess the relationship and relative influence of patient characteristics and site of care on care experiences.

DESIGN

Cohort study.

SETTING

Patients with HIV receiving care outside of emergency rooms, prisons, or the military throughout the continental United States. One thousand seventy-four patients provided ratings of an inpatient stay and 2204 rated an outpatient visit; 818 patients provided evaluations of both inpatient and outpatient care.

PATIENTS

A national probability sample of persons in care for HIV from the HIV Cost and Services Utilization Study.

MEASUREMENTS

Outcome variables were rates of problems with, and global ratings of, inpatient and outpatient care.

RESULTS

Mean problem rates were 20.9% and 8.4% (lower score means fewer problems) for inpatient and outpatient care, respectively. On 9 of 10 of the individual inpatient report items, 15% or more of respondents reported problems. Global ratings of inpatient and outpatient care were 65.3 and 75.0 (0-100 scale, higher scores indicate better ratings), respectively. In multivariable models that controlled for site effects, the only patient characteristic that was consistently associated with problem rates and global ratings of care was mental health (P <0.0001 for both inpatient and outpatient care). Models including site effects explained two to four times as much variance as models excluding site effects.

CONCLUSIONS

Inpatients with HIV reported higher problem rates with inpatient than outpatient care. Better provider-patient communication during inpatient stays is needed. For both inpatient and outpatient care, quality improvement efforts may be most productively focused on providers and processes of care at sites rather than on specific patient subgroups.

Contribution of major diseases to disparities in mortality

BACKGROUND

Mortality from all causes is higher for persons with fewer years of education and for blacks, but it is unknown which diseases contribute most to these disparities.

METHODS

We estimated cause-specific risks of death from data from the National Health Interview Survey conducted from 1986 through 1994 and from linked vital statistics. Using these risk estimates, we calculated potential years of life lost and potential gains in life expectancy related to specific causes, with stratification according to education level and race.

RESULTS

Persons without a high-school education lost 12.8 potential life-years per person in the population, as compared with 3.6 for persons who graduated from high school (ratio, 3.5; P<0.001). Ischemic heart disease contributed most (11.7 percent) to the difference according to education in potential life-years lost (with all cardiovascular diseases accounting for 35.3 percent). All cancers accounted for 26.5 percent, including 7.7 percent due to lung cancer; other lung diseases and pneumonia contributed 10.1 percent of the total, whereas human immunodeficiency virus (HIV) disease accounted for none of the difference according to education. The pattern of disparities according to level of income was similar to that according to level of education. Blacks and whites lost 7.0 and 5.2 potential life-years per person, respectively, as a result of deaths from any cause (ratio, 1.35; P<0.001). Cardiovascular diseases accounted for one third of this disparity, in large part because of hypertension (15.0 percent); HIV disease (11.2 percent) contributed almost as much as ischemic heart disease (5.5 percent), stroke (2.8 percent), and cancer (3.4 percent) combined; trauma and diabetes mellitus accounted for 10.7 percent and 8.5 percent, respectively.

CONCLUSIONS

Although many conditions contribute to socioeconomic and racial disparities in potential life-years lost, a few conditions account for most of these disparities - smoking-related diseases in the case of mortality among persons with fewer years of education, and hypertension, HIV, diabetes mellitus, and trauma in the case of mortality among black persons. These findings have important implications for targeting efforts to reduce existing disparities in mortality rates.

Where to seek care: an examination of people in rural areas with HIV/AIDS

Though HIV/AIDS has spread to rural areas, little empirical evidence is available on where patients living in these areas receive care. This article presents estimates of rural residents in care for HIV/AIDS, their demographic and health-related characteristics, information about whether they receive care in a rural or urban setting, and data on the drug therapies prescribed. The estimates come from the HIV Cost and Services Utilization Study (HCSUS), a nationally representative probability sample of HIV-infected adults receiving care in the contiguous United States. Regardless of the definition used--enrollment site, usual source of HIV care, or site of most recent hospitalization--almost three quarters of rural residents with HIV/AIDS obtained their health care in urban areas. The authors find that differences in the demographic characteristics of those using urban vs. rural care do not drive the decision on where to obtain care, with the primary difference being that people with a rural provider tend to be older. Rural residents with an urban usual source of HIV care incurred significant inconvenience in obtaining care--the majority said their care was not conveniently located, they had substantially longer mean travel times, and over 25% had put off obtaining care in the past 6 months because they did not have a way to get to their provider. Given the considerable burden this places on a chronically ill population,further research is needed to explore how provider supply and provider experience affect the decision to travel for care and how quality of care is affected.

Participation in research and access to experimental treatments by HIV-infected patients

BACKGROUND

Although there is concern that minority groups and women are underrepresented in research involving patients with human immunodeficiency virus (HIV) infection, the available data are inconclusive.

METHODS

We used nationally representative data from the HIV Cost and Services Utilization Study to determine the characteristics of the participants and nonparticipants in trials of medications for HIV infection and whether or not patients had access to experimental treatments. A probability sample of 2864 persons, representing all 231,400 adults with known HIV infection who are cared for in the contiguous United States, were interviewed on three occasions between 1996 and 1998. They were asked about participation in clinical research studies of medications and past receipt of experimental medications for HIV.

RESULTS

We estimate that 14 percent of adults receiving care for HIV infection participated in a medication trial or study; 24 percent had received experimental medications; and 8 percent had tried and failed to obtain experimental treatments. According to multivariate models, non-Hispanic blacks and Hispanics were less likely to be participating in trials than non-Hispanic whites (odds ratio for participation among non-Hispanic blacks, 0.50 [95 percent confidence interval, 0.28 to 0.91]; odds ratio among Hispanics, 0.58 [95 percent confidence interval, 0.37 to 0.93]) and to have received experimental medications (odds ratios, 0.41 [95 percent confidence interval, 0.32 to 0.54] and 0.56 [95 percent confidence interval, 0.41 to 0.78], respectively). Patients who were cared for in private health maintenance organizations were less likely to participate in trials than those with fee-for-service insurance (odds ratio, 0.43 [95 percent confidence interval, 0.21 to 0.88]). Women were not underrepresented in research trials and had a similar likelihood of receiving experimental treatments.

CONCLUSIONS

Among patients with HIV infection, participation in research trials and access to experimental treatment is influenced by race or ethnic group and type of health insurance.

Response to symptoms among a U.S. national probability sample of adults infected with human immunodeficiency virus

Previous studies concerning disparities in Human Immunodeficiency Virus (HIV) services use among vulnerable groups did not control for specific clinical need for care such as symptom events. Using the Andersen Behavioral Model of Health Services Use, the authors determined whether minorities, women, and the less educated (vulnerable groups) were less likely to receive care for HIV symptoms. Persons enrolled in the HIV Cost and Services Utilization Study were asked whether they received care for their most bothersome symptom. Surprisingly, minorities and women were no more likely to go without care than other groups. Those with Medicaid, Medicare, private health maintenance organization (HMO) insurance, or no insurance were less likely to receive care for symptoms than those with private-non-HMO insurance. Vulnerable groups were no less likely to use services for HIV-related symptoms when need for care was considered. However, disparities may exist for symptom-specific care among HIV infected persons covered by public or HMO insurance.

Associations of self-reported oral health with physical and mental health in a nationally representative sample of HIV persons receiving medical care

BACKGROUND

The impact of oral health on HIV patients has not been sufficiently documented.

OBJECTIVE

To estimate the associations between measures of oral and generic health-related quality of life in persons receiving medical care for HIV.

DESIGN

This is a longitudinal study of interview data collected in a probability sample of adults with HIV receiving health care in the US. The data were collected at three points in time.

PATIENTS

Two thousand eight hundred and sixty-four HIV-infected adults using medical care.

MEASUREMENTS

Physical and mental health were assessed using 28 items and oral health was assessed using seven items on oral-related pain and discomfort, worry, appearance, and function. Clinical measures included CD4 count, oral symptoms, physical symptoms, and stage of HIV. Physical functioning and emotional well-being were measured on a 0-100 scale with higher scores indicating better health. Oral health was measured using seven items with a five point scale.

RESULTS

In multivariate analyses, oral symptoms had the strongest association with oral health-related quality of life. Each additional oral symptom was associated with an average decrease in oral health (0-100 possible range) of 3.97 points (p = 0.000). In addition, oral health was significantly associated with both physical and mental health. A one-point increase in oral health was associated with a 0.05 (p = 0.000) increase in mental health and 0.02 increase in physical health (p = 0.031).

CONCLUSIONS

Oral health is strongly associated with physical and mental health but provides noteworthy unique information in persons with HIV infection. Thus, physical and mental health measures of HIV patients should incorporate indicators of oral functioning and well-being.

Specialty training and specialization among physicians who treat HIV/AIDS in the United States

OBJECTIVE

To assess the association of specialty training and experience in the care of HIV disease with HIV-specific knowledge, referral patterns, and HIV-related education activities.

DESIGN

Cross-sectional survey.

SETTING

The United States.

PARTICIPANTS

Physicians caring for patients in the HIV Costs and Service Utilization Study, a study of a probability sample of HIV-infected individuals in the United States.

MEASUREMENTS AND MAIN RESULTS

Measures included physicians' reports of specialty training and HIV caseload, scores on an HIV-specific knowledge test, referral patterns, and attendance rates at HIV-related educational activities. Approximately 72% (379) of the eligible physicians completed a survey. Of these, 152 (40%) had infectious disease (ID) training, and 213 (56%) were generalists; 4% of ID-trained physicians and 37% of generalist physicians did not consider themselves HIV experts. The median current caseloads were 150 and 200 patients for ID experts and generalist experts, respectively. In contrast, the median caseload for non-expert generalists was 5. Mean scores on the knowledge scale were similar for ID and generalist experts (9.0 items correct out of 11 vs 8.5; P=not significant), but lower for generalist non-experts (6.5 items correct; P <.01). Experts had attended more local and national HIV meetings than non-experts (9.3 vs 2.7; P <.01, and 2.3 vs.40; P <.01, respectively) in the past year. Fewer ID experts ever referred than generalist experts (13.0% vs 27.3%; P=.01). In multivariable models that included specialty training and caseload, physicians with caseloads of 20 to 49 and >50 were more likely to have a high knowledge score (defined as 80% or more correct, odds ratio [OR], 2.8; P=.04 and OR, 5.7; P <.001, respectively), and the effect of specialty was attenuated (OR, 2.7; P=.02 decreased from OR, 7.8; P <.001 in a model without caseload). In the models predicting referral practices, both experience (OR,.25; P <.01 and OR,.17; P <.01 for caseloads of 20 to 49 and >50, respectively) and specialty (OR,.19; P <.01 and OR,.09; P <.01 for generalist and ID experts, respectively) were significant.

CONCLUSIONS

In a national sample of physicians, HIV-specific knowledge was more strongly associated with HIV caseload than with specialty training. In addition, although referral practices were related to both experience and specialty, generalist experts and ID physicians reported similar behaviors. This suggests that generalist physicians, through clinical experience and self-education, can develop specialized knowledge in HIV care.

The care of HIV-infected adults in rural areas of the United States

OBJECTIVE

This study describes the population of HIV-infected adults receiving care in rural areas of the United States and compares HIV care received in rural and urban areas.

METHODS

Interviews were conducted with a nationally representative sample of 367 HIV-infected adults receiving health care in rural areas and 2806 HIV-infected adults receiving health care in urban areas of the contiguous United States.

RESULTS

We estimate that 4800 HIV-infected persons received medical care in rural areas during the first half of 1996. Patients in rural HIV care were more likely than patients in urban HIV care to receive care from providers seeing few (<10) HIV-infected patients (38% vs. 3%; p <.001). Rural care patients were less likely than urban care patients to have taken highly active antiretroviral agents (57% vs. 73%; p <.001) or Pneumocystis carinii pneumonia prophylactic medication when indicated (60% vs. 75%; p =.006).

CONCLUSIONS

Few American adults received HIV care in rural areas of the United States. Our findings suggest ongoing disparities between urban and rural areas in access to high-quality HIV care.

Effects of cost sharing on care seeking and health status: results from the Medical Outcomes Study

OBJECTIVES

This study sought to determine the effect of cost sharing on medical care use for acute symptoms and on health status among chronically ill adults.

METHODS

Data from the Medical Outcomes Study were used to compare (1) rates of physician care use for minor and serious symptoms and (2) 6- and 12-month follow-up physical and mental health status among individuals at different levels of cost sharing.

RESULTS

In comparison with a no-copay group, the low- and high-copay groups were less likely to have sought care for minor symptoms, but only the high-copay group had a lower rate of seeking care for serious symptoms. Follow-up physical and mental health status scores were similar among the 3 copay groups.

CONCLUSIONS

In a chronically ill population, cost sharing reduced the use of care for both minor and serious symptoms. Although no differences in self-reported health status were observed, health plans featuring cost sharing need careful monitoring for potential adverse health effects because of their propensity to reduce use of care that is considered necessary and appropriate.

Improvement in emotional well-being and relationships of users of sildenafil

PURPOSE

We estimated the association of sildenafil use with erectile function, relationship with sexual partner, functional status and emotional well-being in men with erectile dysfunction.

MATERIALS AND METHODS

Letters were mailed to eligible patients at a university hospital urology and internal medicine clinic, and university affiliated community primary care clinics by the primary care provider or urologist inviting them to participate in the study. Of the eligible sample 124 men (53%) completed and returned a survey, including 85 who reported current sildenafil use. Change scores in these patients were calculated using the International Index of Erectile Function, marital interaction scale from the Cancer Rehabilitation Evaluation System Short Form, 5-item emotional well-being scale of the RAND 36-Item Health Survey and 12-Item Short Form Health Survey.

RESULTS

Sildenafil users reported an 88% increase in erectile function scores, 60% increase in overall sexual satisfaction and 36% increase in intercourse satisfaction related to the use of sildenafil (p <0.001). Of the respondents 38% indicated that using sildenafil had definitely improved quality of life. Likewise 29% of respondents indicated that using sildenafil had definitely improved the relationship with their partner. With sildenafil there was a statistically significant improvement in the scores of erectile and sexual function (p <0.001), sexual partner relationship (p = 0.007) and emotional well-being (p <0.001). In a multivariate model improved erectile function and sexual partner relationship were each significantly associated with improved emotional well-being (R2 = 0.20, p <0.001).

CONCLUSIONS

Sildenafil users reported significant improvements in erectile and sexual function that were associated with positive changes in emotional well-being and the sexual partner relationships with their sexual partner.

Effect of case management on unmet needs and utilization of medical care and medications among HIV-infected persons

BACKGROUND

Although case management has been advocated as a method for improving the care of chronically ill persons, its effectiveness is poorly understood.

OBJECTIVE

To assess the effect of case managers on unmet need for supportive services and utilization of medical care and medications among HIV-infected persons.

DESIGN

Baseline and follow-up interview of a national probability sample.

SETTING

Inpatient and outpatient medical facilities in the United States.

PARTICIPANTS

2437 HIV-infected adults representing 217 081 patients receiving medical care.

MEASUREMENTS

Outcomes measured at follow-up were unmet need for supportive services, medical care utilization (ambulatory visits, emergency department visits, and hospitalizations), and use of HIV medication (receipt of antiretroviral therapy and prophylaxis against Pneumocystis carinii pneumonia and toxoplasmosis).

RESULTS

At baseline, 56.5% of the sample had contact with a case manager in the previous 6 months. In multiple logistic regression analyses that adjusted for potential confounders, contact with a case manager at baseline was associated with decreased unmet need for income assistance (odds ratio [OR], 0.57 [95% CI, 0.36 to 0.91]), health insurance (OR, 0.54 [CI, 0.33 to 0.89]), home health care (OR, 0.29 [CI, 0.15 to 0.56]), and emotional counseling (OR, 0.62 [CI, 0.41 to 0.94]) at follow-up. Contact with case managers was not significantly associated with utilization of ambulatory care (OR, 0.77 [CI, 0.57 to 1.04]), hospitalization (OR, 1.13 [CI, 0.84 to 1.54]), or emergency department visits (OR, 1.30 [CI, 0.97 to 1.73]) but was associated with higher utilization of two-drug (OR, 1.58 [CI, 1.23 to 2.03]) and three-drug (OR, 1.34 [CI, 1.00 to 1.80]) antiretroviral regimens and of treatment with protease inhibitors or non-nucleoside reverse transcriptase inhibitors (OR, 1.29 [CI, 1.02 to 1.64]) at follow-up.

CONCLUSIONS

Case management appears to be associated with fewer unmet needs and higher use of HIV medications in patients receiving HIV treatment.

Effects of drug abuse and mental disorders on use and type of antiretroviral therapy in HIV-infected persons

OBJECTIVE

To distinguish the effects of drug abuse, mental disorders, and problem drinking on antiretroviral therapy (ART) and highly active ART (HAART) use.

DESIGN

Prospective population-based probability sample of 2,267 (representing 213,308) HIV-infected persons in care in the United States in early 1996.

MEASUREMENTS

Self-reported ART from first (January 1997-July 1997) to second (August 1997-January 1998) follow-up interviews. Drug abuse/dependence, severity of abuse, alcohol use, and probable mental disorders assessed in the first follow-up interview. Adjusted odds ratios (AORs) and 95% confidence intervals (CIs) estimated from weighted models for 1) receipt of any ART, and 2) receipt of HAART among those on ART.

RESULTS

Of our study population, ART was reported by 90% and HAART by 61%. Over one third had a probable mental disorder and nearly half had abused any drugs, but drug dependence (9%) or severe abuse (10%) was infrequent. Any ART was less likely for persons with dysthymia (AOR, 0.74; CI, 0.58 to 0.95) but only before adjustment for drug abuse. After full adjustment with mental health and drug abuse variables, any ART was less likely for drug dependence (AOR, 0.58; CI, 0.34 to 0.97), severe drug abuse (AOR, 0.52; CI, 0.32 to 0.87), and HIV risk from injection drug use (AOR, 0.55; CI, 0.39 to 0.79). Among drug users on ART, only mental health treatment was associated with HAART (AOR, 1.57; CI, 1.11 to 2.08).

CONCLUSIONS

Drug abuse-related factors were greater barriers to ART use in this national sample than mental disorders but once on ART, these factors were unrelated to type of therapy.

Changes in health-promoting behavior following diagnosis with HIV: prevalence and correlates in a national probability sample

Diet, exercise, smoking, and substance use patterns affect the course of illness and quality of life for people with HIV. In interviews with a national probability sample of 2,864 persons receiving HIV care, it was found that most had made health-promoting changes in one or more of these behaviors since diagnosis. Many reported increased physical activity (43%) and improved diet (59%). Forty-nine percent of cigarette smokers quit or cut down; 80% of substance users did so. Desire for involvement in one's HIV care and information seeking-positive coping were the most consistent correlates of change. Other correlates varied by health practice but included health status, emotional well-being, demographics, and attitudes toward other aspects of HIV care. Most people with HIV improve their health behavior following diagnosis, but more might be helped to do so by targeting these behaviors in future interventions.

A comparison of unmet needs for dental and medical care among persons with HIV infection receiving care in the United States

OBJECTIVE

Oral health conditions associated with HIV disease are frequently more severe than those of the general population, making access to both dental and medical care important. Using the domains specified in the Behavioral Model of Health Services Use, this paper examines the correlates of unmet needs for dental and medical care in a nationally representative sample of patients with HIV.

METHODS

This investigation is a cross-sectional study using baseline data from the HIV Cost and Services Utilization Study (HCSUS), the first nationally representative study of persons in care for HIV. Using probability-based techniques, 4,042 people were randomly selected in January 1996, and 2,864 (71%) completed a structured interview that included questions on unmet needs for dental and medical care. Regression analysis was used to identify variables associated with having unmet needs for dental care only, medical care only, and both medical and dental care.

RESULTS

Of the estimated 230,900 people in treatment for HIV in the United States, approximately 58,000 had unmet medical or dental needs based on self-reported data. Unmet dental needs were more than twice as prevalent as unmet medical needs (32,900 vs 14,300), and 11,600 people were estimated to have both types of unmet needs. Multinomial logit regression showed that persons with low income had increased odds of reporting unmet needs for both dental and medical care. The uninsured and those insured by Medicaid without dental benefits had more than three times the odds of having unmet needs for both types of care than did the privately insured.

CONCLUSIONS

To serve both the dental and medical needs of diverse populations affected by HIV disease, greater coordination of services is needed. In addition, state insurance programs for people with HIV should consider the feasibility of expanding their benefit structure to include dental care benefits.

Screening for cervical cancer in HIV-infected women receiving care in the United States

OBJECTIVE

We examined the sociodemographic, clinical and provider factors associated with screening for cervical cancer among HIV-infected women.

METHODS

We studied a national sample representing 43,490 women receiving treatment of HIV infection who completed first follow-up surveys of the HIV Cost and Service Utilization Study (HCSUS). All women were asked, "In the past 12 months, have you had a Pap test?" Women reporting an abnormal Pap test result were asked whether they had been told antibiotics could cure abnormal cells, and whether they were scheduled for another Pap test or for a colposcopy within 3 months.

RESULTS

Of the population represented, 81% had had a Pap test in the past 12 months. Women who reported having a gynecologist and primary care physician at the same clinical site were almost twice as likely (odds ratio, 1.9; 95% confidence interval, 1.3-3.0) as other women to report Pap testing. Among women who reported abnormal Pap test results and were not told antibiotics could cure abnormal cells, 95% were scheduled for a repeat Pap test or colposcopy, but 15% of the women had not received their repeat Pap test or colposcopy.

CONCLUSION

Although Pap test rates and appropriate referral for abnormal findings were high among HIV-tested women, many women with initially abnormal Pap test results did not actually receive follow-up Pap testing or colposcopy. Providing gynecologic care at the same site as primary HIV care would likely improve delivery of needed gynecologic care for women.
